DUMP-CAR.

To all 'whom it may concern.' j

Be it known that I, HERMAN Pains, a citi- Zen of the United States, and resident of Michigan City, county of Laporte, and State of Indiana, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to dump cars especially adapted for carrying minerals, having downwardly-opening doors in the bottom; the object of the invention being to generally improve on the construction of cars of this character with view to securing great strength without increasing the Weight, large carrying capacity, free discharge andstrong and readily-controllable dumping mechanism.

An embodiment of the invention is hereinafter described, and is illustrated in the accompanying drawings, in Which Figure 1 is a detail plan view ofthe improved dump car Fig. 2 is a detail side elevation of the same Fig. 3 is an end elevation of the car; Fig. 4 is a transverse vertical section thereof on the broken line 4-4 of Fig. 1 Fig. 5 is a detail in pers ective of the mechanism for controlling t le' dumping doors; and Fig. 6 is a sectional detail thereof.

The main center sill or girder of the car comprises a pair of channeled beams 10, 11, running the entire length of the car and forming the compression member of the main truss, the tension member of which comprises the truss-rods 12, 13, one of the struts of the truss being shown at 14.

The body bolsters are built upon the central girder and comprise a pair of lateral bolster members, one of Which is shown at 15, extending outwardly from the girder, to the members of which they are securely riveted, and top and bottom plates 16, 17, tying together the two lateral members of the bolster. The body bolster and the end sills 18 extend a little beyond the side walls of the body of the car, and upon their ends there rest a pair of Z-beams 19, 20, the lower flanges 21 of which project outwardly. A pair of channel beams 22, 23, rest upon the upper lianges of the beams 19, 20, their flanges projecting inwardly, and the two sets of beams 19, 20, and 22, 23, constitute the side sills of the car, the u per members of these sills forming also the ower portions of the side walls of the car.

Specification of Letters Patent.

Application filed February`24, 1909.

Patented July 20, 1909.

Serial No. 479,814.

Suitable brackets, as 24, rest upon and are ksecu'red to the bolster members 15, and to the inner faces of the Z-beams 19, 20. While but one of these brackets is shown it will be understood that others are similarly a plied in like positions. The end sills are tied together at intervals throughout the length of the car by means of rods 25 passing through the Z-beams 19, 20.

The upper portions of the side walls of the car may be of Wood, heavy planks, as 26, being used for this purpose and being secured together by means' of vertical corner plates 27 and a plurality of stakes 28, shown and preferably taking the form of Z-bars, the lower ends of which are secured to the channel beams 22, 23, the ends of the rods 25 being shown as passing through them.

Four sills or nailing strips 29, 30, rest up on the central girder, and extend the entire length of the car. Blocks of similar crosssectional form, shown at 31, 32, are placed upon the sill members 15, and upon these several members the iioor 33 is laid, its edges extending under the upper flanges of the Z- beams 19, 20. 15 the floor is supported between the sills 29, 30, and the sides of the car in part by the tie bolts 25 which, as shown, pass through it.

The floor .is provided with numerous door openings, as shown at 34, 35, and these openings are provided with downwardly opening doors 36, hinged adjacent the central girder. Each of the doors comprises a pair of hinge brackets 37, 38, transversely recessed in their upper faces, as shown at 39, 40, cross-bars 41, 42, being fitted within such recesses, and the flooring boards or panel of the door being secured to these cross-bars. Each of the hinge brackets 37 extends downwardly, and its rearward face is obliquely inclined for- Wardly from the pintles of the hinges.

Intermediate of the bolsters The doors are controlled by means of a shaft 43, suitably journaled in boxes 44, secured to the side faces of the central girder, crankarms 45 projecting from this shaft and each carrying at its outer end a roller 46, engaging the cam face 47 of the hinge bracket. This cam face is slightly depressed or recessed adjacent its lower end, as plainly shown in Fig. 4, and the parts are so pro ortioned and positioned that when the rol er'46 engages this depression the door is closed and the pressure transmitted to the crank-arm is directly longitudinal therewith, or differently stated, when the door is closed the crank-arm is on the center. Then the shaft 43 is turned to swing the crank arm upwardly and backwardly, the door is released and opens by its own weight and the weight of the material resting upon it.

The shaft 43 is controlled by means `of a hand lever 48, pivoted in a bracket 49 se cured to the outer face of the end of the car body. This hand lever 48 swings .loosely on the hub 50 of a ratchet wheel 5l, fixed on a square shaft 52 mounted in a pair of sleeves 53, 54, journaled in the bracket 49. Areversible pawl 55, carried by the hand lever 48, cooperates with the teeth of the ratchet wheel 51, these teeth being double faced, permitting the pawl to be thrown to engage the wheel to move it in either direction.

A crank-arm 56, fixed upon the shaft 52, is connected by means of a link 57 with a crankarm 58 fixed upon the shaft 43. The various crank-arms of the door-controlling mechanism are so proportioned that a single movement of the hand lever 48 will open or close the door. Y
